AIR-FEEDING ATTACHMENT FOR COAL-RANGES AND THE LIKE.

Application filed June 30, 1915.

To all whom it may concern:

Be it known that I, RICHARD LACOURSE, a citizen of the United States,residing at Anaconda, in the county of Deerlodge and State of Montana,have invented a new and useful Air-Feeding Attachment for CoaLRanges andthe like, of which the following is a specification.

This invention relates to an air feeding attachment for coal ranges andthe like, one of the objects of the invention being to provide anattachment having means whereby air can be directed therefrom into astove at points either above or below the fuel, the air being admittedto the attachment through a flue extending preferably to a point outsideof the structure in which the stove is located, a novel arrangement ofdampers being provided whereby the flow of air therethrough can becontrolled at all times.

A further object is to provide an attachment which is simple inconstruction and which will not occupy an objectionable amount of spacewhen positioned upon the stove.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the in vention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinventlon.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a vertical transverse section through aportion of a stove and through the attachment in position thereon. Fig.2 is a section on line A-B Fig. 1. Fig. 3 is a section on line CD Fig.2.

Referring to the figures by characters of -reference 1 designates abox-like structure closed at one end while opening into the other endthereof is a flue 2 which may be extended through the wall W of the roomor other structure in which the device is to be used, whereby fresh airmay be supplied to the attachment. The casing 1 has a longitudinalseries of outlet ports 3 in one side wall thereof and extending fromsaid wall are connecting flanges 4:. Guide cleats 5 are formed on orsecured to said side wall of Specification of Letters Patent.

the casing 1 and are slidably engaged by a damper 6 having openings 7adapted to be moved into or out of register with the ports 3 thus to.open or close said ports. The damper 6 has an arm 8 at one end wherebyit can be shifted longitudinally.

Formed in the top of the casing 1 is a longitudinal series of ports 9and guide cleats 10 are formed on or secured to the top of the casingadjacent this series of ports and are slidably engaged by a damper 11having openings 12 adapted to move into or out of register with theports 9. Damper 11 has an arm 13 by means of which it can be readilyshifted longitudinally so as to open or close the ports.

Retaining cleats 14 are formed on or secured to the top of the casing 1and are de tachably engaged by flanges 15 formed along the sides of ahood 16 which extends up wardly from the casing and overhangs the damper11. The longitudinal walls of this hood converge upwardly and merge intothe top and bottom respectively of an outlet flue 17. Although the hoodhas been shown as made in a separate piece from the casing 1, it is tobe understood that if preferred it can be formed integral therewith.This modified construction is so obvious that it is not deemed necessaryto illustrate it.

A damper 18 is arranged within the flue 2 and by means thereof thepassage of air through the flue to the casing 1 can be con trolled.

In Fig. 1 a portion of a range has been illustrated at R, this rangehaving a grate An opening R is formed in the wall of the range below thegrate G and an extension E projects from the range above the grate G.This extension is adapted to receive the flue 17 while the opening R isadapted to receive the flanges 4, these flanges being bent back againstthe inner face of the wall of the range as shown, thus to fasten theattachment securely in place.

When starting a fire, the damper 11 is moved to closed position, whilethe damper 6 is moved to open position. Thus when the damper 18 isopened, fresh air will pass through the flue 2 into the casing 1 andthence through the ports 3 to the interior of the stove below the grateG. After the fire has been well started, damper 6 can be closed,

Oopies of this patent may be obtained for so ,as to allow the fresh airto enter the upper portion of the stove through the flue '1 andeXtension'E, this being true especially when the damper 6 is open, thefresh air supplied to the top of thestove mixing with the unconsumedproducts of combustion within the fire pot and causing them to beconsumed. By closing the damper 6 and opening the damper 11, the burningof fuel in the stove can be checked materially inasmuch as the draftwill thus be shunted around the grate. I

What is claimed is The combination with a stove casing having anopening-in one wall thereof below the grate and an air inlet extensionextending from said wall above the grate, ofa boxlike casing having oneside fitted Within the opening below the grate, retaining flangesextending from said casing and engaging the inner face of the wall,there being ports within the inner sides and within the top of thecasing, a hood extending longitudinally vof the top of the casing andhaving a laterally projeoting outlet extension detachably seated withinthe extension on the Wall of the stove, said top ports opening into thehood, dampers'slidably mounted upon the top and inner wall of the casingfor regulating the fiow of air through the ports, an air five centseach, by addressing the Commissioner 01' Patents, Washington, D.
